Description: Founded in 1904, The Journal of Infectious Diseases is the premier publication in the Western Hemisphere for original research on the pathogenesis, diagnosis, and treatment of infectious diseases, on the microbes that cause them, and on disorders of host immune mechanisms. Articles in JID include research results from microbiology, immunology, epidemiology, and related disciplines. Published for the Infectious Diseases Society of America.

The "moving wall" represents the time period between the last issue
available in JSTOR and the most recently published issue of a journal.
Moving walls are generally represented in years. In rare instances, a
publisher has elected to have a "zero" moving wall, so their current
issues are available in JSTOR shortly after publication.
Note: In calculating the moving wall, the current year is not counted.
For example, if the current year is 2008 and a journal has a 5 year
moving wall, articles from the year 2002 are available.

Terms Related to the Moving Wall

Fixed walls: Journals with no new volumes being added to the archive.

Absorbed: Journals that are combined with another title.

Complete: Journals that are no longer published or that have been
combined with another title.

Abstract

The incubation period of typhoid fever is highly variable, ranging in the cases here recorded f rom 3 to 38 or 40 days. The mean incubation period in different epidemics ranges from 7 ± 0.26 to 19.50 ± 0.31 days, differing significantly from one epidemic to another. The standard deviations range from 1.84 ± 0.18 to 8.85 ± 1.17. The distributions are positively skew. The results here obtained are consonant with the belief that the length of the incubation period depends in part on the virulence of the infection. The means of the epidemics due to infected water are 13.81 ± 0.83, 1938 ± 1.66, and 19.50 ± 0.31, whereas the means for those due to infected food, in which the dose was probably more massive, are 7 ± 0.26 and 9.54 ± 0.39.
